The name of your uploaded file should be as descriptive and relevant as possible. Simply queue one word after another, don't use a "-" or similar inbetween. Please note that file names can't be changed after upload!
There is no Commons standard for files naming. According to the one established by the French-speaking Wikipedia Coats of arms Project, some necessary informations should appear, in this order:
- Coat of arms or Arms, or another word according to your language (Wappen, Stemma, etc.)
- Nature of the holder of arms : city / family / province / etc.
- Country of the holder, by its code : en / fr / de / etc. (give the present country)
- Name of the holder (for a city, it can be followed by the territorial subdivision it belongs to, in brackets). For example : Mex (Vaud)
